When a purse is so large that it is actually the size of a small piece of luggage. A purse/suitcase.
Shante - "Hey, are you on the way to the airport? I didn't know you were going on a trip."

Ashanti - "Yeah, I'm didn't want to have to pay for another check bag so I'm carrying on my purcase."

Guy - "I hate paying $20 for consessions at the movie!"
Girl - "No worries, just stash your treats and soda in my purcase."
